1. Electric Motors Quiet operation realized by proper clearance, recommend fitting practice. Lower noise lubricants. Suitable for all speed ranges applications requiring low noise.

2. Automotive Alternators Longer life in vibrations and high temperature environments.

3. Automotive Starters High reliability in periodic use of vibrations and high temperature environments.

4. Compressors Long life pump rotors which compress air in low temperature and low viscosity lubrication environments.

5. Blowers Quiet and stable operation on fan rotors at high speed, in environments with vibration and high temperatures

6. Transmissions Compact design for light weight to achieve high performance

7. Longer Life Adopted NACHI original seal design to prevent contamination and grease leakage. Contains special grease for wider temperature ranges and longer life.

8.Smooth and Quiet Operation The precision level of our bearing components has been enhanced to ensure smooth and quiet operation.

9.Low Torque Lower rotating torque by improving seal lips
